Part Number: TCAN1057AV-Q1

Hi Expert,

I would like to confirm the limitation for power up/dowm sequence bwtween Vcc and VIO.

I think, TCAN1057AV-Q1 don(t have any limitation for seqence between Vcc and VIO, Is it correct?

Customer usecase, Vcc=5.0V, VIO=3.3V

Thanks

Hi Muk,

You are correct. TCAN1057A does not have any power sequencing requirements for Vcc and Vio. The device will remain in a Protected (or Silent) low power state, keeping the CAN pins in a high impedance state, until both supplies are present.

See datasheet Table 8-2 for more details.

Regards,
Eric Schott
